Fist time use and I found it a definite improvement from last year by just planting tomatoes in the soil. I have a raised bed and the added depth of soil helps. Plus the trees fit right into the halos.

The water drains from the outer reservoir very very slowly if at all. Tomatoes are planted in the ground. Spent significant effort amending the soil under the halos even deeper and wider than in the instructions so I'd have good drainage .... used about 2/3rds lobster compost mix and 1/3rd existing soil. Holes aren't plugged, so unclear why drainage is so poor. Too early for Tomato roots to interfere with the holes. Using stacking tomato ladders ... time will tell as not all that secure as others noted. Now that I have flowers but no tomato set yet, fertilizing inner ring with liquid fertilizer containing calcium. Seems halo design once flowers start is much more suitable to using liquid fertilizer in the inner ring than using slow release granules that may burn the plants.

These halos are just right for both spacing is automatic and the trees fit right into the halos. No weeds and easy to water and feed the individual plants. Be certain to get the red color for your tomatoes they seem to love the extra reflected light in that color. I use the green color for the pepper plants.

PNW weather can be quite unfriendly toward tomatoes. This gadget protects, and properly hydrates your tomato starts as they grow. I team it up with the pop-up tomato accelerator. So far they are thriving.
